THREAD GUIDE.

Application filed January 31, 1924. Serial No. 689,658.

To all whom it nmy concern Be it known that I, CHARLES J AMES BAcoN,

a citizen of the United States, and residing at the city of Buffalo,county of Erie, and 6 State of New York, have invented certain new anduseful Improvements in Thread Guides, of which the following is aspecification.

This invention relates to thread guides such as are particularly adaptedto be used in connection with throwing machines.

One of the primary objects of the invention is to provide a device ofthe character mentioned which is so constructed as to facilitatethreading thereof and permit ready adjustment of the same with respectto the spool or other thread carrying element thus permittingexpeditious renewal or removal of such element.

Another object of the invention is to provide a device of the charactermentioned in combination with a suitable bracket therefor, the twoelements being so constructed as to permit the device to be readilyassembled or disassembled as the occasion may require. Other objects andcertain advantages of the invention will become apparent .from thefollowing description when taken in connection with the accompanyingdrawings in which Figure 1 is a side elevation'of the device embodyingmy invention the same being shown as attached to a suitable support andlocated directly above a spool or other thread carrying element.

Figure 2 is a front elevation of the device.

Figure 3is a plan view of the device as viewed from above in Figure 2.

Figure 4 is a view of the device as seen from beneath in Figure 2.

In the drawings wherein for the purpose of illustration is shown what Iat present consider the preferred form of my invention, the numeral 5indicates a support which may be associated with or constitute a part ofa throwing machine, not shown, with which is also associated a rotatablespindle or other similar member 6, adapted for the reception of a spoolor other thread carrying element indicated as a whole by the numeral 7from which the thread 8 is adapted to be removed or thrown by reason ofrotation of the spool through the instrumentality of the spindle uponwhich the same is held. This thread, upon being thrown from the spool 7is given a whirling motion which corresponds in direction to that of thespool 7, and as a result of such whirling motion, the thread is thrownoutwardly in the form of a loop 8, revolving about the axis of thespindle and describing in effect an oblate spheroid or substantiallysuch a geometric figure. The thread, upon being removed from the spool,as a result of the whirling action to which the same is subjected, isgiven a twisting action, the extent of which is determined by the rateat which the thread is wound upon a suitable reel, spool or other threadreceiving unit, not shown. As the thread is passing from the spool 7 tothe above mentioned thread receiving or winding mechanism, it is guidedin its course of travel by means of an adjustable, quick detachable andreadily threaded guide, indicated as a whole by the numeral 9. Thisguide is preferably constructed from suitable spring wire which is bentintermediate its ends to provide a pair of legs 10 and 11 arranged in aparallel relation with respect to each other. The leg 10 at its lowerend is bent at right angles to provide a stop 12 whereas the other leg11 is similarly bent to provide an arm 13. This arm is curved as shownat 14.- forming a connector or connecting element arranged at an anglewith respect to the arm 13 as shown most clearly in Figures 1 and 2. Theconnector is bent upon itself to provide a yoke 15 which terminates in afinger 16 arranged in a parallel relation with respect to the arm 13 andprojecting an appreciable distance beyond the adjacent portion of thearm 13, which with the connector 14, yoke 15 and finger 16 forms ineffect an eyelet indicated as a whole by the numeral 17. By reason ofthe fact that the eyelet 17 is so formed and inasmuch as the finger 16is spaced an appreciable distance from the arm 13 it will be readilyappreciated that-the thread 8 may be easily introduced into the eyeletby first placing the thread at. the rear of the eyelet, as indicated bythe dotted line shown in Figure 1, and thereafter bringing the upper endor portion of the thread forward through the space afforded between thefinger 16 and arm 13, and under the projecting finger. The leg 10 beingsomewhat shorter than the leg 11 assures clearance for the thread.

The guide 9 is attached to the support 5 by means of a bracket 19 and isadapted for vertical adjustment therein. This bracket comprises a base20 which may be secured to the support 5 by means of screws 21 and is sobent at opposite ends as to provide ledges or flanges 22, one of whichis formed with an elongated opening 23 adapted for the reception of thelegs 10 and 11 whereas the other is cut away to provide wings or lugs 24embracing or engaging the legs 10 and 11. The wire from which the guide9 is formed is more or less resilient and due to such inherentresiliency the legs 10 and 11 which. are connected together by means ofa yoke 18 formed integral therewith are normally urged outwardly intoengagement with the flange 22 and the lugs 24 by reason of whichengagement the device as a unit is frictionally held in a given adjustedposition. The spaced flanges 22 prevent any longitudinal rockingmovement of the guide 9, while the engagement of the parallel legs 10and 11 with these flanges in the manner above described prevents anyhorizontal swinging movement of the eyelet-carrying arm 13, so thatthereby the eyelet 17 during operation is securely held in position overthe spool 7 and substantially in alignment with the spindle 6, as shownin Fig. 1.

In throwing machines of the type with which the device embodying myinvention is adapted to be used, it is customary to employ a battery ofspools or other thread carrying elements, from which the thread isthrown in the manner hereinbefore described. These spools are arrangedrelatively close to each other, and while the thread must be thrown asuflicient distance to clear the upper heads or flanges of the spools,one of which heads is indicated by the numeral 7, care must be exercisedto prevent the thread from being thrownso far outwardly as to interferewith the whirlmg thread of the adjacent spool. With the device embodyingmy invention the distance to which the thread is thrown from the spoolmay be varied between limits, depending upon the distance at which theeyelet 17 is maintained from the spool. I have found that the eyelet maybe maintained in its lowermost position, shown in Figure 1, representinga distance from the spool equal to approximately one and a quarterinches to obtain satisfactory results when a battery or row of spoolsare employed, which are placed approximately six inches from each other.e

In view of the fact that the eyelet 17 is maintained relatively close tothe spool 7 during operation, it becomes necessary to move the guide toits uppermost position,

shown in Figure 2, so that clearance maybe afforded between the deviceand-the spool when ,it is desired to remove the empty spool, from whichthe thread has been unwound.

' With the eyelet positioned' as shown in Fig- ,ment is bent over atright angles to the legs 10 and 'filled with thread substituted for theprevious spool after which the guide is again lowered to its positionshown in Figure 1.

Upward movement of the guide.9 is limited by the stop 12 while itsdownward movelimited by the yoke 18, which is In order to introduce theguide into the bracket 19, the leg 10 is passed upwardly through theopening 23, after which the eyelet or yoke 18 is so worked through theopening as to allow the leg 11 to enter'therein, the leg 10 now beingfree. The guide is then moved upwardly to permit the leg 11 to enter thespace afforded between the lugs 24. With the guide raised the leg 10 maythen be introduced into the space a-fi'orded between the lugs 24, afterwhich the guide is moved downwardly to permit the leg 10 to entertheopening 23, the leg 10 of course being so sprung as to permit the stop12 to clear the lower flange 22 as the leg 10 enters the opening 23 andassumes a parallel position with respect to the leg 11, as shown. Toremove the guide from its bracket the above mentioned steps are, ofcourse, carried out in a reverse order. It will be appreciated that byreason of the peculiar construction of the bracket and guide, removaland substitution, such as is necessary due to occasional injury to thedevice, may be executed expeditiously thus obviating the necessity forlong delays in the operation of the throwing machine in so far as anyparticular'spool and reeling mechanism is concerned.
